Traffic, 2008
Plant endosomes are highly dynamic organelles that are involved in the constitutive recycling of plasma membrane cargo and the trafficking of polarized plasma membrane proteins such as auxin carriers. In addition, recent studies have shown that surface receptors such as the plant defense‐related FLS2 receptor and the brassinosteroid receptor BRI1 ...

Homotypic fusion between early endosomes can be reconstituted in vitro. By using wortmannin and LY294002, inhibitors of phosphatidylinositol (Pl) 3-kinase, a requirement for this activity has been established in order for fusion to proceed efficiently.

The delivery of endocytosed cargo to lysosomes occurs through kissing and direct fusion of late endosomes/MVBs (multivesicular bodies) and lysosomes. Live-cell and electron microscopy experiments together with cell-free assays have allowed us to describe the characteristics of the delivery process and determine the core protein machinery required for ...

Endosomal Signaling and Oncogenesis
2014The endosomal system provides a route whereby nutrients, viruses, and receptors are internalized. During the course of endocytosis, activated receptors can accumulate within endosomal structures and certain signal-transducing molecules can be recruited to endosomal membranes.

The biogenesis of multivesicular endosomes
Nature Reviews Molecular Cell Biology, 2004Recent progress has been made in our understanding of the molecular mechanisms that regulate the biogenesis of multivesicular transport intermediates in the degradation pathway that leads to lysosomes. Here, we discuss recent work that uncovers some of the mechanisms that cause both membrane invagination within these newly forming intermediates and the

The transforming growth factor beta (TGFβ) signaling pathway is important for normal cell homeostasis and has critical roles in apoptosis, cell-cycle arrest, and cellular differentiation (reviewed in Massague, 2008). In the classical TGFβ pathway, the endosomal trafficking of receptors has a direct outcome on signal transduction-receptors internalized ...

During the development of the nervous system, neurons respond to diffusible cues secreted by target cells. Because such target-derived factors regulate development, maturation, and maintenance of axons as well as somatodendritic compartments, signals initiated at distal axons must be retrogradely transmitted toward cell bodies. Neurotrophins, including

Multivesicular Bodies and Multivesicular Endosomes: The "Ins and Outs" of Endosomal Traffic
Science's STKE, 2002Multivesicular endosomes (MVEs) are complex intracellular organelles that function in endocytosis. A major function of the endocytic pathway is to sort internalized macromolecules and membrane proteins. Appropriately sorted proteins, such as epidermal growth factor (EGF) receptor (EGFR), are incorporated into MVEs before transport to the lysosomal ...

Acidification of Lysosomes and Endosomes
1996Lysosomes, endosomes, and a variety of other intracellular organelles are acidified by a family of unique proton pumps, termed the vacuolar H(+)-ATPases, that are evolutionarily related to bacterial membrane proton pumps and the F1-F0 H(+)-ATPases that catalyze ATP synthesis in mitochondria and chloroplasts.

Annexins and Endosomal Signaling
2014Cell signaling and endocytosis are intimately linked in eukaryotic cells. Signaling receptors at the cell surface enter the endocytic pathway and continue to activate downstream effectors in endosomal compartments. This spatiotemporal regulation of signal transduction provides opportunity for signal diversity and a cell-specific machinery of ...
